How to indicate there was an error in the code in App designer stand alone app?

I have some GUI that I created in app designer.
When something wrong (for example I loaded a file with wrong format) - I get an error in the app designer.
But in stand alone app - I can't see the error and can't see any indication that there was an error.
I cannot predict all possible errors.
But I want to see the error text in the stand alone app. Is there some way to show it?

Hello,
As Adam said, it's not so easy. You can use a TextArea and Button component to trigger the callback to load the logfile in the text area. You'll need to figure out how to get the file path of log file. The fact that you have to click the button to load the file is not the best way, maybe you could do it with ButtonDownFcn callback, with every click to load the log file which is still not the best solution.
function ReadCmdWindow(app)
cmdWindowString = fileread('logfile.txt');
app.CommandWindowOutputTextArea.Value = cmdWindowString;
end
If you want to click a button that runs something, and there are prerequisites that needs to be fullfilled, like a value in the EditField component. You can write if statement that checks if some entries are missing, show an alert with uialert function.
Also, you can pop the warning/errors using try and catch with uialert. It works really nice. If you have Optimization toolbox, you can check my uioptimoptions to see the uialerts.
